what is a "Customization key" ?

Not to pick on him, but Erik Garrison wrote:

http://wiki.laptop.org/go/Customization_key doesn't say what a 
"customization key" is.
   "The customization key allows you to install your own set of 
activities and library content on top of a signed OLPC build. You may 
want to include a named activity pack in such a key. ...
   Preparing the key: ...
   Using the key:"
Is this referring to cryptography and signed builds, or is it just a $20 
USB flash drive?

My best guess is the first sentence of Customization_key should read

   "A customization key is a USB flash drive with special boot files 
that upon reboot will install activities, and optionally a new OS image, 
from the USB flash drive onto an XO."

Correct?

I think you mean "USB flash drive" here yet there are USB security 
dongles and encrypted USB flash drives.  If it ain't cryptography, avoid 
the "key" word.

Thanks for any clarification, I'll improve the wiki.
